powerful M21586Q DSP chipThe K17 features an M21586Q DSP chip which is capable of double- precision 64-bit floating-point calculations, and runs at high 380MHz clock frequency. This chip is complemented by a high-performance ES9821Q ADC as well as a specially customized ultra-low phase noise femtosecond crystal oscillator. These three components allow the user, in all modes, to utilize the 31-band high-precision lossless PEQ. The PEQ is designed to ensure the audio signal is still of high fidelity even after being processed. The chip also allows for robust output protection functionality, ensuring that headphones and other connected audio equipment are always fully protected.

greater channel separation and dynamicsIn the K17 is the flagship AKM DAC chip combination – AK4191+AK4499EX*2. Two AK4499EX chips handle each channel. The 8-channel to 4-channel LPF design reduces common mode interference, resulting in better channel separation and dynamics. It also features a newly designed architecture with fully separated digital/analog portions, which also incorporates the newly developed “DWA ROUTING” technology for an even cleaner audio background and improved resolution.

high-performance ES9821Q ADCThe K17 features an M21586Q DSP chip which is capable of double-precision 64-bit floating-point calculations, and runs at a high 360MHz clock frequency. This chip is complemented by a high-performance ES9821Q ADC as well as a specially customized ultra-low phase noise femtosecond crystal oscillator. These three components allow the user, in all modes, to utilize the 31-band high-precision lossless PEQ. The PEQ is designed to ensure the audio signal is still of high fidelity even after being processed.

When adjusting PEQ on the K17, PCM 44.1k~96k signals can be originally processed. Fine adjustments of audio parameters are thus possible, allowing for adjustments such as a gain range of +12~-24dB and a Q value range of 0.4dB~128dB. The PEQ allows the user to simulate or correct the frequency response curve PEQ settings can be easily exported, imported, shared, and saved – making it easy for anybody to use the PEQ and correct or simulate various frequency response curves of different headphones.
